SIEBENBERGER, ISAAC BEN DAVID:

Russian Hebraist; died at Warsaw April 2, 1879. He occupied himself especially with apocryphal literature, his translations into Hebrew and Judæo-German including the following: "Ḥayye Ṭobiyah" (Warsaw, 1839), a translation of the Book of Tobit; "Megillat Yehudit" (ib. 1840), the Book of Judith and other narratives; "Sefer Baruk" (ib. 1841), the Book of Baruch and the prayers of Manasseh and of Daniel's three companions; and "Sifre Makkabi" (ib. 1843), the Books of the Maccabees. To all these translations he added Hebrew commentaries and introductions.
